1 Introducing the ZyAIR
The ZyAIR B-G2000 is a broadband sharing gateway with a built-in wireless LAN access point and four-
port switch that makes it easy for people to set up a small home/office network and share Internet access via
a broadband (cable/DSL) modem. Key features of the ZyAIR include 802.1x wireless LAN security, WPA
(Wi-Fi Protected Access), firewall, remote management and UPnP. See your User’s Guide for more details
on all ZyAIR features.
You should have an Internet account already set up and have been given most of the following information.

2 Hardware Connections
2.1 Side Panel and Connections
LABEL DESCRIPTION AND FUNCTION
1. LAN Use an Ethernet cable to connect at least one computer for initial ZyAIR configuration.
These ports are auto-negotiating (can connect at 10 or 100Mbps) and auto-crossover
(automatically adjust to the type of Ethernet cable you use (straight-through or
crossover)).
2. WAN Connect your cable/DSL modem to this port with the cable that came with your modem.
3. POWER
12V DC
Connect the end of the included power adaptor (use only this adaptor) to this power
socket.
After you’ve made the connections, connect the power cable to a power supply and look at the front panel
LEDs.
RESET You only need to use this button if you’ve forgotten the ZyAIR’s password. It returns the
ZyAIR to the factory defaults (password is 1234, LAN IP address 192.168.1.1 etc. see
your User’s Guide for details).

3 Setting Up Your Computer’s IP Address
Skip this section if your computer is already set up to accept a dynamic IP
address. This is the default for most new computers.
The ZyAIR is already set up to assign your computer an IP address. Use this section to set up your
computer to receive an IP address or assign it a static IP address in the 192.168.1.2 to 192.168.1.254 range
with a subnet mask of 255.255.255.0. This is necessary to ensure that your computer can communicate with
your ZyAIR.
Your computer must have a network card and TCP/IP installed. TCP/IP should already be installed on
computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems. Refer to the Setting
Up Your Computer’s IP Address appendix in the User’s Guide for configuring the IP address in other
operating systems.
3.1 Windows 2000/NT/XP
1. In Windows XP, click Start, Control Panel. In Windows 2000/NT, click Start, Settings, Control
Panel.
2. In Windows XP, click Network Connections.
In Windows 2000/NT, click Network and Dial-up Connections.
3. Right-click Local Area Connection and then click Properties.
4. Select Internet Protocol (TCP/IP) (under the General tab in Windows XP) and click Properties.
5. The Internet Protocol TCP/IP Properties screen
opens (the General tab in Windows XP).
-To have your computer accept a dynamic IP address,
click Obtain an IP address automatically.
-If you want a static IP address, click Use the
following IP Address and fill in the IP address (use
one between192.168.1.2 and 192.168.1.254), Subnet
mask (255.255.255.0), and Default gateway
(192.168.1.1) fields.
Click Advanced.

you do not know your DNS server IP address(es).
If you know your DNS server IP address(es), click Use
the following DNS server addresses, and type them
in the Preferred DNS server and Alternate DNS
server fields.
If you have previously configured DNS servers, click
Advanced and then the DNS tab to order them.

3.2 Checking/Updating Your Computer’s IP Address
1. In the computer, click Start, (All) Programs, Accessories and then Command Prompt.

computer’s static IP address is in the correct subnet (in the range between 192.168.1.2 and
192.168.1.254 if using the default ZyAIR LAN IP address). Alternatively, to have the ZyAIR assign
your computer a new IP address (from the IP pool), make sure your ZyAIR is turned on, type
"ipconfig/renew" and then press ENTER.
